The opposite ends of the cross bar 33 have sleeves 35 of resillent material -which are adapted to contact with the innerfaces of the window frame from being marred when-the" platform-is in use.

The boards 22 are at various levels and the upper board rests upon the horizontal tubular members 10.

By having these supporting different levelsthe person using the platform board according to the work being performed. Thecross rod 26.not only keeps the side frames at the proper distance apart but serves as a back board 22 is being used.

The device may be readily set up and positioned on a window frame and building as indicated in Fig. 2 without injuring any part of the building or window frame and quickly dismembered and'will occupy very little space when being transported from one position to an-' other. l

It is obvious also thatthe platform may be adjusted to accommodate it to various widths of windows.

.By making the sideframes of tubular metal members connected by brace rods welded thereto, very rigid side frames are'insure'd capable of sustaining great weight, v

claim The platform may be used bywindow washers, painters, carpenters and other mechanics -imd wh n once installed may be used with absolute safety.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described our, invention,we
